connection drop with IPv6 Privacy Extensions



Hi,

from time to time, with my IPv6 tunnel, I had random SSH connection drops (at least when idle), but did not find out what the culprit was. I've changed firewall settings, tunnel types, tried another server, added client keepalive settings, but to no avail.

Now I've discovered that it seems to be related to the IPv6 Privacy Extensions that assign a random IP every once in a while. When I have static IPv6 assigned via radvd, it works like a charm.

Is this a known issue? Is there a workaround?
Is it related to my iptables timeout configuration, or maybe a local problem on my (Mac) client?

The error message on the router always is "icmpv6_send: no reply to icmp error".

If anyone made similar experiences, let me know.

Thanks,
Florian
